南昌航空大学实验报告年月日课程名称：面向对象程序设计实验名称：类与结构班级：学生姓名：学号：指导教师评定：签名：1、实验目的·学习掌握声明和定义类及成员。·学习掌握访问类对象成员。·学习掌握保护数据如何屏蔽外部访问的原理，更好的认识类的封装2、实验内容(1)定义一个满足下列要求的Date类：①用下面的格式输出日期：日/月/年②可运行在日期上加一天操作③设置日期#include<iostream.h>#include<iomanip>usingnamespacestd;classDate{public:voidDisplay();voidSetDay(intyear,intmonth,intday);voidAddOneDay();protected:boolLegal(intyear,intmonth,intday);boolIsLeapYear(intyear);intyear;intmonth;intday;};boolDate::IsLeapYear(intyear){return((year%4==0&&year%100!=0)||(year%400==0));}boolDate::Legal(intyear,intmonth,intday){if(month<=0||month>12)return0;if(IsLeapYear(year)){if(month==2){if(day<=0||day>29)return0;}else{if(month==1||month==3||month==5||month==7||month==8||month==10||month==12){if(day<=0||day>31)return0;}else{if(day<=0||day>30)return0;}}}else{if(month==2){if(day<=0||day>28)return0;}else{if(month==1||month==3||month==5||month==7||month==8||month==10||month==12){if(day<=0||day>31)return0;}else{if(day<=0||day>30)return0;}}}return1;}voidDate::Display(){cout<<year<<"/"<<month<<"/"<<day<<"\n";}voidDate::SetDay(inty,intm,intd){cout<<"pleaseinputy,m,d:\n";cin>>y>>m>>d;year=y;month=m;day=d;if(!Legal(year,month,day)){cout<<"error\n";}}voidDate::AddOneDay(){day++;if(!Legal(year,month,day)){day=1;if(month==12){year++;month=1;}elsemonth++;cout<<year<<"/"<<month<<"/"<<day<<"\n";}elsecout<<year<<"/"<<month<<"/"<<day<<"\n";}voidmain(){inty;intm；intd;DateD;while(1){D.SetDay(y,m,d);D.Display();D.AddOneDay();}}(2)定义一个时间类Time，能提供和设置由时、分、秒组成的时间，并编出应用程序，定义时间对象，设置时间，输出该对象提供的时间。并将类定义作为接口，用多文件结构实现之。//Time.hclassTime{public:Time();voidPrint();voidSet(int,int,int);protected:intmin;intsec;inthour;};//time.cpp#include<iostream.h>#include"Time.h"Time::Time(){min=23;sec=20;hour=18;}voidTime::Print(){cout<<hour<<":"<<min<<":"<<sec<<endl;}voidTime::Set(ints,intm,inth){cout<<"pleaseinputthetime:"<<"\n";cin>>h>>
